Benefits of technology

[0006]The invention provides a scroll type compressor. A pressure-regulating mechanism thereof adjusts the compression ratio improving efficiency.
[0012]Preferably, the separator comprises a ring pin for preventing leakage of the pressurized airflow.

Problems solved by technology

The conventional scroll type compressor, however, has a constant volumetric ratio and compression ratio, thus, over-compression or under compression results in degrading efficiency of the conventional scroll type compressor.

Embodiment Construction

[0027]The following description is of the best-contemplated mode of carrying out the invention. This description is made for the purpose of illustrating the general principles of the invention and should not be taken in a limiting sense. The scope of the invention is best determined by reference to the appended claims.

[0028]Referring to FIG. 1, the scroll type compressor 1 comprises a housing 10, a frame 20, a compartment 30, a separator 40, a scroll pairs 50, a slider 60, two compartments 70, at least a pressure-regulating mechanism 80 and a guiding element 90. The housing 10 comprises a flow inlet 11 and a flow outlet 12. The frame 20 is fixed in the housing 10. The compartment 30 is disposed in the housing 10 and separated into a high-pressure compartment 31, a low-pressure compartment 32 and a middle-pressure compartment 33 disposed therebetween. The separator 40 is disposed between the high-pressure compartment 31 and the low-pressure compartment 32, and above the scroll pairs ...

Abstract

A scroll type compressor is disclosed. The scroll type compressor includes a housing, a frame, a compartment, a separator, a scroll pairs, a slider, a plurality of compartments, at least a pressure-regulating mechanism, and a guiding element. The compartment in the housing is separated into a high-pressure compartment, a low-pressure compartment, and a middle-pressure compartment. The separator is disposed between the high-pressure compartment and the low-pressure compartment. The separator includes an outlet at the center thereof, and at least a passage through the separator. When the pressure in the high-pressure compartment is less than that in low-pressure compartment, the pressure-regulating mechanism is opened to exhaust pressure from the middle-pressure compartment to the high-pressure compartment.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The invention relates to a scroll type compressor, and more particularly to a scroll type compressor having a pressure adjusting valve.[0003]2. Description of the Related Art[0004]A conventional scroll type compressor is a positive displacement and constant speed compressor. The volumetric ratio and the compression ratio are constant. When the variation of load causes the inlet and outlet pressure to change, the volumetric ratio and the compression ratio must also change. The conventional scroll type compressor, however, has a constant volumetric ratio and compression ratio, thus, over-compression or under compression results in degrading efficiency of the conventional scroll type compressor.[0005]U.S. Pat. No. 6,913,488 discloses a compressor with a device load adjustor. The compressor includes a slider and a scroll for adjusting load variation to maintain a constant compression ratio. The inlet pressure is compressed ...
